Coyote

In this bluffing game by Spartaco Albertarelli you always see the cards of the others, but never your own. When it's your turn, you must announce a number that is less than the total of all the cards in the game, increasing the previous number. Alternatively, you can challenge the number previously announced. Finally, when all the cards are revealed, it is revealed who has the cunning Coyote on their side.
